Problems solved by technology

However, these antibacterial agents are deficient in antibacterial efficiency, speed, broad spectrum, durability, heat resistance, compatibility, processing performance, toxicity, irritation, etc.
In addition, once fibers and nonwovens have antibacterial functions, other quality indicators will be lost to varying degrees; and the production cost will increase greatly due to the high price of antibacterial masterbatches.

Abstract

The invention discloses an antibiotic polypropylene resin composition. The antibiotic polypropylene resin composition comprises a polypropylene resin and additives, and a weight ratio of the polypropylene resin to the additives is 1000:3.5-4.23; the additives comprise a composite antiseptic, a lubricant and an antioxidant, a weight ratio of the antiseptic to the lubricant to the antioxidant is 1:(1.43-1.56):(1.07-1.67), and the composite antiseptic is composed of pyrithionc zinc and 2,4,4'-trichloro-2'-hydroxydiphenyl ether according to a weight ratio of 1:0.125-0.27. The invention also discloses a preparation method of the antibiotic polypropylene resin composition. The antibiotic polypropylene resin composition has the characteristics of good antibiosis rate, broad antibiosis spectrum, lasting antibiosis, use safety, superior physical and mechanical performances, high cost performance and the like, and has a good economic benefit.

Description

technical field [0001] The invention relates to a composition with polypropylene resin as a base material and a preparation method thereof, in particular to a high-performance antibacterial modified polypropylene resin composition developed by adding additives such as antibacterial agent, lubricant and antioxidant through melt mixing. Background technique [0002] In daily activities, people inevitably come into contact with all kinds of bacteria, fungi and other microorganisms. These microorganisms can multiply rapidly and spread diseases through contact and other ways, affecting people's health and normal work, study and life. Since the 1970s, tens of millions of people have died due to bacterial infection. Daily necessities, especially packaging and decoration materials, are seriously moldy, which has brought great harm to human health and brought considerable economic losses to nonwoven fabric manufacturers. In developed countries such as Japan, the antibacterial ratio ...
